Jannik Sinner extended his remarkable run with a 7-5 7-6 (7-4) win over Alex Michelsen at the Miami Open.
The Italian world number two claimed his 25th and 26th straight successes at ATP Masters 1000 events during his win over Corentin Moutet on Monday - setting a new record.
Sinner duly made it 27 but, having taken the first set 7-5, he was 5-2 down in the second before coming back to win on a tie-break.
The four-time Grand Slam winner has triumphed at the past two Masters 1000 tournaments - at Indian Wells earlier this month and Paris in November - without losing a set.
